Undertail Exhaust On A 5Th Gen - Need Help

I know it has been done, but can't find any threads.  Can someone point me in the right direction.  I would consider this if it could be done well.

Veefer800Canuck, this was an impressive install.  I am hugely impressed and continue to study your first-rate install detailed in the link below:

You're welcome sir. Good luck and looking forward to see what you come up with.

There are others... namely, mine, and sa1713's, both of which used Laser end cans and Erion or TBR full exhaust headers.  Search for our threads/galleries.  Wolf is long gone, but I suspect that the guy that did ours would still be able to whip up a set or two...

Ciao,

Ciao,

Dan can also fabricate for 5th gen OEM headers too.

Does anyone that's built an undertail build the pans to sell? I would dearly love to put an undertail on my 98, but just don't have the time to fab the pan. I can get it coated and get the pipes fabbed, but not the pan.

Dan fabricated my underseat pan as well.  A very nice bit he made.  Give him a call.

I actually did a CAD drawing of my underseat pan, if you can have someone build it.

Edit. I guess I had previously posted it in the gallery. May be hard to interpret but I have a full sized version if you need.

Very cool, Cap'n.

While we're on the subject, aside from aesthetics, is there any reason to (or not to) go with a particular muffler setup?  I most often see dual mufflers employed, but from a style perspective, I prefer the OEM single unit you might find under a 600RR or Duc.  Assuming the geometry fits, is there any reason not to use one of these?

The muffler(s) need to be as small vertically as possible, or you're gonna have issues with the rear wheel hitting the exhaust.

That's why my Devil cans work, they are small diameter.

Know off-hand what they diameter of your muffler is?  Or if I can be even more annoying, the minimum clearance between the tire and the muffler?

I can take a couple measurements for you. BRB.

My mufflers are approx 3-3/8" diameter, no more than 3.5" for sure. And they are mounted as high up as possible.

Clearance between the tire and mufflers is approx 4.5", and I have my rear ride height jacked to the max.

Interesting..  I have some maths to do..

Thanks a bunch for the quick measurements, Canuck!

I've got an old thread detailing the install process. Hopefully the photos will help:

Oh yes, I've read through that post.  Huge help.  Just wanted to get those measurements down (perhaps I missed them in your original post).

I tried a 2006 cbr600rr under-tail and had too many clearance and heat issues. I had even "massaged" the can to no avail. And I run 35mm of shock bolt spacers to raise the rear and it still rubbed on occasion.
